Abstract
A 3-D printed cartridge was fabricated using acrylonitrile-butadiene-styrene (ABS) printer filament. The cartridge was printed with an internal helical honeycomb channel pattern - providing a high surface area suitable for flow chemistry. The internal chamber of the cartridge was treated with fuming sulfuric acid to anneal the surface and functionalize the material with sulfonic acid groups. The 3-D printed catalyst was then used in a variety acid-catalyzed organic reactions, with conversions in 52-97% yields.
